2000 Toyota Celica Question: Heater blower not getting power
It is very possible that the problem is in the control as you say. If you have someone that knows how to remove the control and jump the wires to check it out for you. I would do that first it will be the switch with the off and on function. The heater resistor control the blower speeds, not the on and off function. The control switch sends power to the resistor then powers the fan to the correct speed. If this checks out ok check for a broken wire or bad terminal end at the plug. - torque wrench
Could be; trace the wiring back to find out where power has been lost. It would be advisable to check the wiring connectors very closely at the blower motor and resistor, as damaged or melted terminals can cause open circuits. - DaveJHM
